Prevention of damping-off of seedling seedlings
The seedling damping-off disease is caused by Rhizoctonia solani in the soil. Most pathogenic bacteria invade the roots of the seedlings from the surface soil, and the diseased parts of the plants collapsed and contracted after being victimized. The diseased plants were dark brown, and the diseased seedlings often fell down from the soil surface, causing the collapse phenomenon (so-called damping-off disease); As a result, diseased seedlings often do not fall flat and show symptoms of standing dryness. When the soil is wet, the disease department often produces a pink mold layer. This disease has often occurred in our city's Lanzhou branch seedlings, Duying, Cedarwood, etc., causing serious deaths in severe cases. It is also prone to occur during high temperatures in summer. Control methods: 1. In the early stage of seedling disease, 70% thiophanate-methyl wettable powder 1000 times liquid and enemy cough 1000 times liquid can be used for irrigation, which can play the role of sterilizing and protecting seedlings. 2, timely removal and treatment of diseased plants, reduce the source of infection. 3. It is advisable to use formalin for soil disinfection before sowing or planting. 50 liters of formalin per square metre, water 16-24 kilos of water in the soil, or ferrous sulphate, per acre 15 kg, mixed with sand and sprinkled in the soil.
